Adjusting audio level of multiple tracks

In Camtasia 8, you could select multiple clips and hit the Volume Up or Volume Down button to adjust them all at once. The green line moved, so you could see relatively how much the volume level of a track was changed from the starting point. In Camtasia 9, when you adjust the gain, the size of the audio wave changes, but the green line does not move. So there is no way to know by looking at a several tracks if the level was changed from the starting place of the clip. Changing the green line does not change the Gain level. In fact there is a wider range of adjustment by using both the Gain level and the volume line separately. If there a way in Camtasia 9 to adjust the volume of multiple tracks at once as you could with Camtasia 8? How can you know if a track has been changed from its original level and by how much?
